Abstract
A Distributed Antenna System employs a downlink transmission method that requires limited channel information feedback and less coherency between signals than is required for information broadcast. Distributed antennas are treated as diversity antennas with a given power allocation. Each antenna can transmit to multiple UEs by transmitting a weighed sum of their signals, and multiple antennas can transmit to one UE by transmitting weighed space-time (or space-frequency) coded signals. The power allocation weights are determined as an optimum power allocation policy with per-antenna power constraints.
